oracle和mysql数据库的批量update在mybatis中配置不太一样:
oracle数据库:
<update id="batchUpdate" parameterType="java.util.List">
<foreach collection="list" item="item" index="index" open="begin" close="end;" separator=";">
update test
<set>
test=${item.test}+1
</set>
where id = ${item.id}
</foreach>
</update>
mysql数据库:
mysql数据库采用一下写法即可执行,但是数据库连接必须配置:&allowMultiQueries=true
例如: jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
<update id="batchUpdate" parameterType="java.util.List">
<foreach collection="list" item="item" index="index" open="" close="" separator=";">
update test
<set>
test=${item.test}+1
</set>
where id = ${item.id}
</foreach>
</update>
